Pub 无法删除条目，因为它正在被另一个进程使用

Question

我试图将我的 Flutter 项目配置为在网络上运行。flutter channel master我尝试运行后使用切换到主通道flutter upgrade。我现在得到一个无限循环：

Building flutter tool...
Running pub upgrade...
Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)

Waiting for 0 seconds, press CTRL+C to quit ...

Terminate batch job (Y/N)? Y

我尝试了多种方法，例如运行flutter clean、尝试切换回稳定通道、删除 flutter/bin 目录中的缓存文件夹、关闭 Windows Defender，但似乎没有任何效果。现在，当我尝试运行flutter doctor或任何其他 flutter 命令时，我会得到带有相同消息的相同无限循环。我还尝试手动下载并用新安装替换我的 flutter sdk 安装，这也不起作用。此时我唯一的选择是完全删除 flutter 并从头开始重新安装吗？

如果有任何有关如何解决此问题的建议，我将不胜感激。

我以管理员身份运行编译器，它对我有用。以管理员身份打开 Android Studio 或 Visual Studio。

我遇到了这个问题，发现问题是我添加的新依赖项。就我而言，它是assets_audio_player: ^3.0.3+1，但当然它可以是任何依赖项。删除它立即解决了我的问题。

面临这个问题，必须在终端运行“start ms-settings:developers”。它解决了这个问题。

在 Windows 上：以管理员身份运行 vscode 或您正在使用的终端来解决问题。对于 Linux：我认为某种 sudo 方法可以解决这个问题。
